P355N steel grade is a normalized, weldable fine grain steels for pressure purposed. The dimensions and tolerance on dimensions should be according to EN 10028-3.P355N mean the room temperature, P355NH means the elevated temperature quality. P355NL1 means the low temperature quality, P355NL2 means the special low temperature quality.
we also can supply P355NH,P355NL1,P355NL2,please contact us if you need.
